Description
The present invention relates to method and the monitoring device of movement for monitoring at least one door, especially elevator door.This
Bright further to elevator device, described elevator device includes the device of the movement for monitoring it.
Elevator device includes at least one lift car that at least one hoistway and the length along described hoistway move respectively.
Mobile door it is provided with at hoistway and car, thus when lift car location is against landing zone, it is allowed to passenger is at different floors
On change between the landing zone that described hoistway and lift car are formed.In order to ensure the safety operation of elevator device,
Needed reliably to close door, in order to prevent passenger from crashing into hoistway before lift car starts to move.
Because door includes the Mechanical Moving element that can suffer careless passenger's abrasion and/or damage, so described door is frequent
The fault that can cause elevator device, the key component shut down or blockade.
Accordingly, it would be beneficial to be movement to elevator door to be monitored constantly, be not only the fault/envelope of detection door
Resistance, but also before blockading detection go out movement subtle disruption in case allow blockade generation and elevator device stop completely
Before machine, opposite house places under repair.
In accordance with an exemplary embodiment of the invention, vision sensor (picture recording device) is provided at and allows opposite house
The functional position exercised supervision, thus inspection door and/or the movement of door lock, in order to when the actual movement of door deviates significantly from door
When predetermined (preferable) is mobile, send the message such as such as warning/alarm signal.
In accordance with an exemplary embodiment of the invention, it is used for monitoring the prison of the movement of at least one door, especially elevator door
Survey device includes: (a) at least one picture recording device or vision sensor, and it is arranged to the movement at least one
Period records at least one of multiple pictures of at least one；B () storage device, it is arranged to store multiple reference
Picture；And (c) comparison means.Described comparison means is arranged to deposit at least one in the picture of record with being stored in
At least one in reference picture in storage device is compared to determine diversity factor, and for when diversity factor is beyond predetermined pole
Sending message in limited time, described diversity factor represents the difference between picture and at least one reference picture of at least one storage.
The exemplary of the present invention farther includes elevator device, and described elevator device includes: hoistway, it is at base
This vertical side upwardly extends；At least one lift car, it is arranged to move along the length of hoistway；At least one can move
Dynamic door；And monitoring device in accordance with an exemplary embodiment of the invention, it is for monitoring at least one movement described.
Monitoring device can be arranged to monitor the movement of the door of lift car.Alternatively, or in addition, elevator device includes at least one
Individual hoistway door, and described monitoring device is arranged to monitor the movement of described hoistway door.
The method bag of at least one door of monitoring in accordance with an exemplary embodiment of the invention, the especially movement of elevator door
Include following steps:
(A) the mobile period at described elevator door records at least one of multiple pictures of at least one；
(B) reference picture of the picture of record Yu storage being compared to determine diversity factor, described diversity factor represents
Difference between picture and the reference picture of storage；
(C) described diversity factor is compared with preset limit；And
(D) if diversity factor is beyond preset limit, message is sent.Described message is probably warning message or alert message.
It is the most right that the exemplary of the present invention being described the most in more detail allows
The position of the mobile parts of elevator door is monitored, thus allows to carry out error-detecting and predictive maintenance, because so allowing
Carried out fast reaction maintenance and/or changed affected parts, so shortening the shutdown of elevator device before generation of blockading
Time.Because monitoring the state of elevator constantly, so detecting interference in early days and keeping the performance of elevator and position accurate
Property.
This improves the elevator device availability for passenger, and reduce cost of serving, thus it is full to strengthen client
Meaning degree.
The method proposed is applicable to the elevator of all kinds, especially has central opening type door and the electricity of telescopic door
Ladder.
With reference to accompanying drawing, disclosure of the invention will become better understood by.

Row compares, and described comparison means 19 is probably a part for elevator controlling part.This compares can provide corresponding single door by application
The standard method of the image evaluation of movement difference degree performs, and described diversity factor represents the picture of record in single door moving process
And the difference between the previously stored reference picture of mobile door.
Then, described single door movement difference degree is compared with at least one preset limit, and if described difference
Different degree then sends the caution signals indicating described door 6,16 the most correctly to open and/or close or alarm signal beyond preset limit.
In accordance with an exemplary embodiment of the invention, there is at least two otherwise limit, and when beyond first (under) pole
Send in limited time and require attendant to check elevator to avoid the caution signals damaged further, and when beyond second (on) pole
Stop the operation of elevator device 1 in limited time and prevent any further movement of lift car 8, because in this case, electricity
Any further operation of ladder system is considered to be unsafe.
Fig. 6 is schematically illustrated the illustrative methods of the already described above picture analyzing record, the top of described Fig. 6
The storage with constant time lag T being carried out symbolization on a period of time t of the mobile period of door 6,16 by rectangle shown partially
Reference picture.
The actual picture recorded in the mobile period of door schematically shows in the low portion of Fig. 6.At t2, t5, t7
At t8, between previously stored reference picture and the image of physical record, there is not the actual movement of concordance instruction door 6,16
Deviation expection (preferable) is mobile.To send warning signal or alarm signal according to the quality and quantity of deviation.
Described method may further comprise determining that the position of the respective labels 22 in the picture of record, in order to determines hoistway 2
The upright position of interior lift car 8.If described position exceeds precalculated position, then can adjust electricity before opening door 6,16
The physical location of ladder car 8, and/or the warning/alarm signal requiring that elevator device 1 is safeguarded can be sent.
Step described by can repeating at each floor 4 of lift car 8 process, in order to continuously ensure that lift car
Safety operation.
